Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, and specifically relates to a scientific and technological kinetic energy fitness bike. Background Art

[0002] In the prior art, the longitudinal adjustment of the exercise bike seat is mostly fixed and loosened by a manual knob, and both hands are required to adjust it, which is troublesome and complicated. Moreover, most exercise bike seats do not have a lateral adjustment mechanism, which reduces the user's satisfaction with the multi-directional adjustment. In addition, most of the existing exercise bike pedals do not have safety protection. When the user pedals too fast, the foot is easy to fall off the pedal, which can easily cause injury. In addition, most exercise bikes are assembled on site and are inconvenient to move after installation.

[0003] The Chinese patent with publication number CN221155246U discloses a new type of fitness bike. The patent adjusts the handle upward, and the handle pulls the adjustment rope, which drives the hook card to rotate. The hook protrusion of the hook card is separated from the second positioning hole, and the seat can be quickly adjusted up and down. The reset of the hook card is performed by a spring. When the adjustment handle is relaxed, the hook card is quickly pulled back to its original position due to the tension of the spring, and the hook protrusion of the hook card is fixed on the second positioning hole. The clamping step prevents the first longitudinal adjustment tube from moving downward, thereby realizing the rapid longitudinal adjustment of the product seat. The adjustment can be easily performed with one hand, and the adjustment is simple, which improves the user experience. At the same time, the lateral adjustment can also be performed, which greatly improves customer satisfaction. Safety protection is set at the pedal to improve safety performance. Pulleys are set for easy movement, but the physical fitness of users is different, and the training intensity is also different. The device cannot adjust the strength of the fitness bike when exercising, and cannot meet the needs of users. Moreover, the fitness bike is easy to occupy the space at home when idle, which hinders people from walking.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a scientific and technological kinetic energy fitness vehicle to solve the problems raised in the above-mentioned background technology.

[0009] Optionally, a drive wheel and a resistance wheel are provided inside the drive box, and the drive wheel and the resistance wheel are connected by a transmission belt.

[0010] Optionally, the bottom end of the resistance block is arc-shaped, and the bottom end of the resistance block penetrates through the top wall of the drive box and abuts against the resistance wheel.

[0011] Optionally, the armrest column is rotatably connected to the support frame through a rotating shaft, the fixing column penetrates through the support frame and is inserted into the fixing hole, and the fixing column is threadedly connected to the support frame.

[0014] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the present utility model does not necessarily need to achieve all the advantages described below:

SPECIFIC IMPLEMENTATION MANNERS

[0026] Now, the present utility model will be further described in detail in conjunction with the accompanying drawings.

[0027] Please refer to Figures 1-4As shown in the figure, in this embodiment, a scientific and technological kinetic energy fitness bike is provided, including a base 1. A support frame 3 is connected to the top of the base 1. A drive box 4 is connected between the support frames 3. The support frames 3 can be used to support the drive box 4 and connect the armrest column 5. And the support frame 3 is rotatably connected with a pedal, and the pedal is connected to a drive wheel in the drive box 4. A card slot 14 is opened on the side wall of the base 1. A support block 2 is connected to the card slot 14 opened on the side wall of the base 1. An inner cavity 12 is opened inside the support block 2. Slide grooves 10 are opened on both side walls of the inner cavity 12 to guide the sliding of the clamping block 13. A spring 15 is connected inside the inner cavity 12. The side wall of the spring 15 is connected with a clamping block 13. The clamping block 13 can be moved into the card slot 14 by the acting force of the spring 15. The clamping block 13 and the card slot 14 can fix the support block 2. A slider 8 is connected to the side wall of the clamping block 13. Moving the slider 8 can drive the clamping block 13 to move, and then the clamping block 13 is separated from the card slot 14. An armrest column 5 is installed at the top of the support frame 3. Fixing holes 11 are opened on the front and rear side walls of the armrest column 5. A fixing column 9 is inserted into the fixing holes 11. The armrest column 5 can be fixed by the fixing column 9 and the fixing holes 11. A resistance block 6 is located above the drive box 4. A screw rod 7 is connected to the top of the resistance block 6. The resistance block 6 can increase the resistance of the resistance wheel to realize the adjustment of the movement resistance of the fitness bike.

[0028] In this embodiment, an extension block is provided on the right side of the top of the support frame 3. The screw rod 7 passes through the extension block and is threadedly connected to the extension block. The bottom end of the screw rod 7 is threadedly connected to the top of the resistance block 6. A drive wheel and a resistance wheel are provided inside the drive box 4, and the drive wheel and the resistance wheel are connected by a transmission belt. The bottom end of the resistance block 6 is arc-shaped, and the bottom end of the resistance block 6 penetrates the top wall of the drive box 4 and abuts against the resistance wheel.

[0029] The extension block on the right side of the top of the support frame 3 provides support and guidance for the screw rod 7. The screw rod 7 passes through the extension block and is threadedly connected to it, so that the screw rod 7 can move up and down along the thread of the extension block when rotating. The bottom end of the screw rod 7 is threadedly connected to the top of the resistance block 6. Such a design enables the up and down movement of the screw rod 7 to directly drive the corresponding up and down movement of the resistance block 6. The drive wheel is driven by the pedal, and the resistance wheel is used to adjust the difficulty of the movement. They are connected by a transmission belt, so that the power of the drive wheel can be transmitted to the resistance wheel. The bottom end of the resistance block 6 is arc-shaped, and this shape helps to contact and apply pressure to the resistance wheel more evenly. The bottom end of the resistance block 6 penetrates the top wall of the drive box 4 and abuts against the resistance wheel. When the resistance block 6 moves up and down, it will change the pressure on the resistance wheel, thereby adjusting the size of the resistance;

[0030] For example, when it is necessary to increase the resistance of the fitness bike, rotate the screw rod 7 to move it downward, drive the resistance block 6 downward, increase the pressure on the resistance wheel, and increase the resistance during the transmission process. On the contrary, rotate the screw rod 7 to move it upward, reduce the pressure of the resistance block 6 on the resistance wheel, and reduce the resistance.

[0031] In this embodiment, the armrest column 5 is rotatably connected to the support frame 3 through a rotating shaft, enabling the armrest column 5 to rotate relative to the support frame 3 around the rotating shaft. When the fitness bike is idle, the armrest column 5 can be rotated along the rotating shaft to achieve a storage effect, reducing the occupation of space by its own volume. The fixing column 9 passes through the support frame 3 and is inserted into the fixing hole 11 of the armrest column 5, and the fixing column 9 is threadedly connected to the support frame 3. When the fixing column 9 is tightened, it can firmly fix the armrest column 5 at the current angular position, preventing accidental rotation of the armrest column 5 during use. When the angle of the armrest column 5 needs to be adjusted again, just loosen the fixing column 9 so that it no longer tightly fixes the armrest column 5, and then the angle can be adjusted.

[0032] In this embodiment, there are four card slots 14 and support blocks 2, which are respectively located on the front and rear side walls of the base 1 and are symmetrically distributed. Such a quantity and distribution method can provide support and stability to the base 1 from multiple positions, enabling the base 1 to be more balanced and stable when bearing pressure and force. The top wall of the support block 2 is rotatably connected to the base 1, and the support block 2 can rotate towards the top of the base 1, thereby achieving a folding effect. The left side wall of the spring 15 is fixedly connected to the left inner wall of the inner cavity 12, and the right side wall of the spring 15 is fixedly connected to the latch 13. The spring 15 can apply a rightward elastic force to the latch 13. When the latch 13 is subjected to an external leftward pressure, the spring 15 will be compressed. When the external pressure disappears, the elastic force of the spring 15 will push the latch 13 back to its original position. The sliders 8 are located on the front and rear sides of the latch 13, and the sliders 8 are located in the sliding grooves 10, ensuring the stability and directionality of the latch 13 during movement and preventing the latch 13 from deviating or skewing during movement. The latch 13 corresponds to the card slot 14, and the latch 13 can be inserted into the card slot 14 under the action of the spring 15, thereby achieving the fixing function;

[0033] For example, when the fitness bike is in use, the support block 2 can be rotated to align the support block 2 horizontally with the base 1. The latch 13 is inserted into the card slot 14 under the push of the spring 15 to achieve the stable support of the support block 2. When the fitness bike is idle, manually press the latch 13 to compress the spring 15 and disengage from the card slot 14, and then fold the support block 2 towards the top of the base 1 to reduce the space occupied by the fitness bike.

[0034] When the user uses the exercise bike, the user steps on the pedals, and the pedals drive the driving wheels in the driving box 4 to rotate. The driving wheels transmit power to the resistance wheels through the transmission belt. If the exercise resistance needs to be adjusted, the screw rod 7 can be rotated. The screw rod 7 moves up and down under the action of the thread in the extension block. Because it is threadedly connected to the top end of the resistance block 6, it drives the resistance block 6 to move up and down. When the resistance block 6 moves downwards, the arc-shaped bottom end thereof increases the pressure on the resistance wheel, thereby increasing the resistance during the transmission process and increasing the exercise intensity; conversely, when the resistance block 6 moves upwards, the pressure on the resistance wheel is reduced, the resistance is decreased, and the exercise intensity is reduced.

[0035] During use, the handrail column 5 is inserted into the fixing hole 11 through the fixing column 9 to ensure the stability of the handrail column 5 during use.

[0036] The support block 2 of the base 1 plays a role in stabilizing the overall structure. During use, the support block 2 is rotated to be horizontally aligned with the base 1, and the latch 13 is inserted into the card slot 14 under the push of the spring 15 to achieve stable support. When it is idle, the latch 13 is manually pressed to disengage it from the card slot 14, and the support block 2 is folded towards the top end of the base 1 to reduce space occupation.

[0037] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
